RDP - external method - error

[bohemian]

Does any body know, why I can not log in virtual machine (runnig on the host system Windows XPP SP3) by „external“ authentication method? I don´t get any login screen - Only error on connection message after a several sec.
When I use „null“ method, it always goes without any problem.

I conect to vm from another windows PC on local network using windows RDP to „host´s IP:5000“
I had tried both NAT even Bridged network mode. NET card is default.
Host´s firewall is switched-off.

Thank you very much.

IMHO Several things can keep this from working.
For external Auth to work the .VirtualBox folder that has the "VRDPAuth.dll " in it needs to be in the path statement so Windows can find it.
If you are using the Windows RDP program you must put a checkmark in the allow me to store my credentials.
You must use a login name that is valid on the windows machine.

Thank you very much for your advice.

The problem was in checkmark "Allow me to store my credentials"
Everything goes well right now.

The instalator of V.Box put the path of VirtualBox install folder to the paths of system variables by default. I checked it and I found it there
